Summary Gene frequencies at 16 blood group and protein polymorphism loci (A, C, D, K, P, Q, U, Al, Gc, Es, A1B, Tf, PGD, PGM, GPI and Pi) are given for three horse breeds in Morocco (Arabian, Arab‐Barb and Barb). These data are used to calculate average heterozygosity ( h ), Nei's standard genetic distance (D N ) and probability of exclusion (PE). Variability expressed as the average heterozygosity was lower in the Arabian (0.330 ± 0.066), while it was higher and almost the same in the Arab‐Barb (0.413 ± 0.071) and the Barb (0.414 A ± 0–070). The shortest genetic distance was found between Barb and Arab‐Barb. The 16 loci used are at least 95% effective for recognizing incorrect paternity in these breeds. The Barb and Arab‐Barb genetic profiles obtained showed the rare variants interesting perhaps in the context of European and American breeds: notably D cfgkm , D dekl , Es‐N, Tf‐A and Pi‐W.
